I. Product Overview

WOODWARD 5439-861 is an inductive 12-slot modular control rack specifically designed for Woodward control system platforms such as NetCon 5000, MicroNet, 723/723+. It serves as the physical carrier and backplane for the control system, providing mechanical support, electrical connections, and data communication buses for all inserted CPUs, I/O, power supplies, communications, etc. It is the core fundamental component for building distributed control systems. 

II. Core Functional Characteristics

12-slot Standard Architecture: Provides 12 standard slots, supporting mixed insertion of the entire series of Woodward control modules.

Passive Backplane Design: No active electronic components, extremely high reliability, and extremely low failure rate.

Multi-platform Compatibility: Perfectly compatible with NetCon 5000, MicroNet, 723, 723+ control systems.

High-speed Data Bus: Integrated redundant backplane bus to ensure high-speed and stable data interaction between modules.

Redundant Power Supply Support: Supports dual independent power input, achieving N+1 or 1:1 power redundancy.

Module Compatibility: Supports mixed installation of new and old modules, facilitating smooth system upgrade and transformation.

EMC Electromagnetic Shielding: Full-metal sealed chassis, providing excellent anti-interference and electromagnetic shielding capabilities.

Industrial-grade Structure: High-strength metal material, shock-resistant, dust-proof, and suitable for harsh industrial environments.

Hot Swap Support: Combined with dedicated modules, supports online hot swap maintenance, without requiring system shutdown.
